How Doctors Responded to Being Named a Leading Killer

Sept 19 Doctors copy.jpeg

In my video Why Prevention Is Worth a Ton of Cure, I profiled a paper that added up all the deaths caused by medical care in this country, including the hundred thousand deaths from medication side effects, all the deaths caused by errors, and so on. The author of the paper concluded that the third leading cause of death in America is the American medical system.

What was the medical community's reaction to this revelation? After all, the paper was published in one of the most prestigious medical journals, the Journal of the American Medical Association, and was authored by one of our most prestigious physicians, Barbara Starfield, who literally wrote the book on primary care. When she was asked in an interview what the response was, Starfield replied that her primary care work had been widely embraced, but her findings on how harmful and ineffective healthcare could be received almost no attention.

This inspires the recollection of "the dark dystopia of George Orwell's 1984, where awkward facts are swallowed up by the 'memory hole' as if they had never existed at all." Report after report has come out, and the response has been a deafening silence both in deed and in word, failing to even openly discuss the problem, leading to thousands of additional deaths. We can't just keep putting out reports, we have to actually do something.

As I discuss in my video How Doctors Responded to Being Named a Leading Killer, the first report was published in 1978, suggesting about 120,000 preventable hospital deaths a year. The response? Silence for another 16 years until another scathing reminder was published. If we multiply 120,000 by those 16 years, we get 1.9 million preventable deaths, about which there was near total doctor silence. There was no substantial effort to reduce the number of those deaths. The Institute of Medicine (IOM) then released its landmark study in 1999, asserting that yet another 600,000 patients died during that time when providers could have acted.

Some things have finally changed. Work hour limits were instituted for medical trainees. Interns and residents could no longer be worked more than 80 hours a week, at least on paper, and the shifts couldn't be more than 30 hours long. That may not sound like a big step, but when I started out my internship, I worked 36 hour shifts every three days, 117-hour work weeks.

When interns and residents are forced to pull all-nighters, they make 36% more serious medical errors, five times more diagnostic errors, and have twice as many "attentional failures." That doesn't sound so bad, until you realize that means things like nodding off during surgery.

The patient is supposed to be asleep during surgery, not the surgeon.

Performance is impaired as much as a blood alcohol level that would make it illegal to drive a car--but these overworked interns and residents can still do surgery. No surprise there were 300% more patient deaths. Residents consider themselves lucky if they get through training without killing anyone. Not that the family would ever find out. With rare exceptions, doctors are unaccountable for their actions.

The IOM report did break the silence and prompted widespread promises of change, but what they did not do is act as if they really believed their own findings. If we truly believed that a minimum of 120 people every day were dying preventable deaths in hospitals, we would draw a line in the sand. If an airliner was crashing every day, we'd expect that the FAA would step in and do something. The Institute of Medicine could insistently demand that doctors and hospitals immediately adopt at least a minimum set of preventive practices--for example, bar-coding drugs so there aren't any mix-ups, like they do for even a pack of Tic Tacs at the grocery store. Rather than just going on to write yet another report, they could bluntly warn colleagues they would publicly censure those who resisted implementing these minimum practices, calling for some kind of stringent sanctions.

Instead, we get silence. But not for Barbara Starfield, who is unfortunately no longer with us. Ironically, she may have died from one of the adverse drug reactions she so vociferously warned us about. She was placed on aspirin and the blood-thinner Plavix to keep a stent she had to have placed in her coronary artery from clogging up. She told her cardiologist she was bruising more, bleeding longer, but those side effects are the risks you hope don't outweigh the benefits. Starfield apparently hit her head while swimming and bled into her brain.

The question for me is not whether she should have been on two blood-thinners for that long or even whether she should have had the stent inserted. Instead, I question whether or not she could have outright avoided the heart disease, which is 96% avoidable in women.

The number-one killer of women need almost never happen.


For those curious about my time in medical training, you can read my memoir of sorts, Heart Failure: Diary of a Third Year Medical Student.

It isn't just medical treatment that can be harmful. Even medical diagnosis can be dangerous, as I discuss in my video Cancer Risk From CT Scan Radiation.

And, just as we're (finally) seeing some changes in training protocols, the times, they are a-changin' with the emergence of the field of lifestyle medicine, as I present in several videos, including:

I recently made some videos to give people a closer look at why I believe it's so important for us to take responsibility for our own health. You can see all of them on our new Introductory Videos page.

Plant-Based Diets as the Nutritional Equivalent of Quitting Smoking

The Best Kept Secret in Medicine.jpeg

Despite the most widely accepted and well-established chronic disease practice guidelines uniformly calling for lifestyle change as the first line of therapy, doctors often don't follow these recommendations. As seen in my video, The Best Kept Secret in Medicine, lifestyle interventions are not only safer and cheaper but often more effective in reducing heart disease and failure, hypertension, stroke, cancer, diabetes, and deaths from all causes than nearly any other medical intervention.

"Some useful lessons may come from the war on tobacco," Dr. Neal Barnard wrote in the American Medical Association's ethics journal. When he stopped smoking himself in the 1980s, the lung cancer death rate was peaking in the United States. As the prevalence of smoking dropped, so have lung cancer rates. No longer were doctors telling patients to "[g]ive your throat a vacation" by smoking a fresh cigarette. Doctors realized they were "more effective at counseling patients to quit smoking if they no longer had tobacco stains on their own fingers." "In other words, doctors went from being bystanders--or even enablers--to leading the fight against smoking." And today, says Dr. Barnard, "Plant-based diets are the nutritional equivalent of quitting smoking."

From an editorial in the journal Alternative Therapies in Health and Medicine: "If we were to gather the world's top nutrition scientists and experts (free from food industry influence), there would be very little debate about the essential properties of good nutrition. Unfortunately, most doctors are nutritionally illiterate. And worse, they don't know how to use the most powerful medicine available to them: food."

Physician advice matters. When doctors told patients to improve their diets by cutting down on meat, dairy, and fried foods, patients were more likely to make dietary changes. It may work even better if doctors practice what they preach. Researchers at Emory University randomized patients to watch one of two videos. In one video, a physician briefly mentioned her personal dietary and exercise practices and visible on her desk were both a bike helmet and an apple. In the other video, she did not discuss her personal healthy practices, and the helmet and apple were missing. In both videos, the doctor advised the patients to cut down on meat, not usually have meat for breakfast, and have no meats for lunch or dinner at least half the time. In the disclosure video, the physician related that she herself had successfully cut down on meat. Perhaps not surprisingly, patients rated that physician to be more believable and motivating. Physicians who walk the walk--literally--and have healthier eating habits not only tend to counsel more about exercise and diet, but have been found to seem more credible or motivating when they do so.

It may also make them better doctors. A randomized controlled intervention to clean up doctors' diets, called the Promoting Health by Self Experience (PHASE) trial, found that healthcare providers' personal lifestyles were correlated directly with their clinical performance. Healthcare providers' improved wellbeing and lifestyle cascaded to the patients and clinics, suggesting an additional strategy to achieve successful health promotion.

Are you ready for the best kept secret in medicine? Given the right conditions, the body can heal itself. For example, treating cardiovascular disease with appropriate dietary changes is good medicine, reducing mortality without any adverse effects. We should keep doing research, certainly, but educating physicians and patients alike about the existing knowledge regarding the power of nutrition as medicine may be the best investment we can make.

Of course, to advise patients about nutrition, physicians first have to educate themselves, as it is unlikely they received formal nutrition education during their medical training:

How to Treat High Blood Pressure with Diet

How to Treat High Blood Pressure with Diet.jpeg

High blood pressure ranks as the number-one risk factor for death and disability in the world. In my video, How to Prevent High Blood Pressure with Diet, I showed how a plant-based diet may prevent high blood pressure. But what do we do if we already have it? That's the topic of How to Treat High Blood Pressure with Diet.

The American Heart Association, the American College of Cardiology, and the Centers for Disease Control and Prevention recommend lifestyle modification as the first-line treatment. If that doesn't work, patients may be prescribed a thiazide diuretic (commonly known as a water pill) before getting even more meds until their blood pressure is forced down. Commonly, people will end up on three drugs, though researchers are experimenting with four at a time. Some patients even end up on five different meds.

What's wrong with skipping the lifestyle modification step and jumping straight to the drugs? Because drugs don't treat the underlying cause of high blood pressure yet can cause side effects. Less than half of patients stick with even the first-line drugs, perhaps due to such adverse effects as erectile dysfunction, fatigue, and muscle cramps.

What are the recommended lifestyle changes? The AHA, ACC, and CDC recommend controlling one's weight, salt, and alcohol intake, engaging in regular exercise, and adopting a DASH eating plan.

The DASH diet has been described as a lactovegetarian diet, but it's not. It emphasizes fruits, vegetables, and low-fat dairy, but only a reduction in meat consumption. Why not vegetarian? We've known for decades that animal products are significantly associated with blood pressure. In fact, if we take vegetarians and give them meat (and pay them enough to eat it!), we can watch their blood pressures go right up.

I've talked about the benefits to getting blood pressure down as low as 110 over 70. But who can get that low? Populations centering their diets around whole plant foods. Rural Chinese have been recorded with blood pressures averaging around 110 over 70 their whole lives. In rural Africa, the elderly have perfect blood pressure as opposed to hypertension. What both diets share in common is that they're plant-based day-to-day, with meat only eaten on special occasion.

How do we know it's the plant-based nature of their diets that was so protective? Because in the Western world, as the American Heart Association has pointed out, the only folks getting down that low were those eating strictly plant-based diets, coming out about 110 over 65.

So were the creators of the DASH diet just not aware of this landmark research done by Harvard's Frank Sacks? No, they were aware. The Chair of the Design Committee that came up with the DASH diet was Dr. Sacks himself. In fact, the DASH diet was explicitly designed with the number-one goal of capturing the blood pressure-lowering benefits of a vegetarian diet, yet including enough animal products to make it "palatable" to the general public.

You can see what they were thinking. Just like drugs never work--unless you actually take them. Diet never work--unless you actually eat them. So what's the point of telling people to eat strictly plant-based if few people will do it? So by soft-peddling the truth and coming up with a compromise diet you can imagine how they were thinking that on a population clae they might be doing more good. Ok, but tell that to the thousand U.S. families a day that lose a loved one to high blood pressure. Maybe it's time to start telling the American public the truth.

Sacks himself found that the more dairy the lactovegetarians ate, the higher their blood pressures. But they had to make the diet acceptable. Research has since shown that it's the added plant foods--not the changes in oil, sweets, or dairy--that appears to the critical component of the DASH diet. So why not eat a diet composed entirely of plant foods?

A recent meta-analysis showed vegetarian diets are good, but strictly plant-based diets may be better. In general, vegetarian diets provide protection against cardiovascular diseases, some cancers, and even death. But completely plant-based diets seem to offer additional protection against obesity, hypertension, type-2 diabetes, and heart disease mortality. Based on a study of more than 89,000 people, those eating meat-free diets appear to cut their risk of high blood pressure in half. But those eating meat-free, egg-free, and dairy-free may have 75% lower risk.

What if we're already eating a whole food, plant-based diet, no processed foods, no table salt, yet still not hitting 110 over 70? Here are some foods recently found to offer additional protection: Just a few tablespoons of ground flaxseeds a day was 2 to 3 times more potent than instituting an aerobic endurance exercise program and induced one of the most powerful, antihypertensive effects ever achieved by a diet-related intervention. Watermelon also appears to be extraordinary, but you'd have to eat around 2 pounds a day. Sounds like my kind of medicine, but it's hard to get year-round (at least in my neck of the woods). Red wine may help, but only if the alcohol has been taken out. Raw vegetables or cooked? The answer is both, though raw may work better. Beans, split peas, chickpeas, and lentils may also help a bit.

Kiwifruits don't seem to work at all, even though the study was funded by a kiwifruit company. Maybe they should have taken direction from the California Raisin Marketing Board, which came out with a study showing raisins can reduce blood pressure, but only, apparently, compared to fudge cookies, Cheez-Its, and Chips Ahoy.

The DASH diet is one of the best studied, and it consistently ranks as US News & World Report's #1 diet. It's one of the few diets that medical students are taught about in medical school. I was so fascinated to learn of its origins as a compromise between practicality and efficacy.

I've talked about the patronizing attitude many doctors have that patients can't handle the truth in:

Treating Kidney Stones with Diet

Treating Kidney Stones with Diet.jpeg

Studies suggest that excessive consumption of animal protein poses a risk of kidney stone formation, likely due to the acid load contributed by the high content of sulfur-containing amino acids in animal protein, a topic I explore in my video, Preventing Kidney Stones with Diet. What about treating kidney stones, though? I discuss that in How to Treat Kidney Stones with Diet. Most stones are calcium oxalate, formed like rock candy when the urine becomes supersaturated. Doctors just assumed that if stones are made out of calcium, we simply have to tell people to reduce their calcium intake. That was the dietary gospel for kidney stone sufferers until a 2002 study published in the New England Journal of Medicine pitted two diets against one another--a low-calcium diet versus a diet low in animal protein and salt. The restriction of animal protein and salt provided greater protection, cutting the risk of having another kidney stone within five years in half.

What about cutting down on oxalates, which are concentrated in certain vegetables? A recent study found there was no increased risk of stone formation with higher vegetable intake. In fact, greater dietary intake of whole plant foods, fruits, and vegetables were each associated with reduced risk independent of other known risk factors for kidney stones. This means we may get additional benefits bulking up on plant foods in addition to just restricting animal foods.

A reduction in animal protein not only reduces the production of acids within the body, but should also limit the excretion of urate, uric acid crystals that can act as seeds to form calcium stones or create entire stones themselves. (Uric acid stones are the second most common kidney stones after calcium.)

There are two ways to reduce uric acid levels in the urine: a reduction of animal protein ingestion, or a variety of drugs. Removing all meat--that is, switching from the standard Western diet to a vegetarian diet--can remove 93% of uric acid crystallization risk within days.

To minimize uric acid crystallization, the goal is to get our urine pH up to ideally as high as 6.8. A number of alkalinizing chemicals have been developed for just this purpose, but we can naturally alkalize our urine up to the recommended 6.8 using purely dietary means. Namely, by removing all meat, someone eating the standard Western diet can go from a pH of 5.95 to the goal target of 6.8--simply by eating plant-based. As I describe in my video, Testing Your Diet with Pee & Purple Cabbage, we can inexpensively test our own diets with a little bathroom chemistry, for not all plant foods are alkalinizing and not all animal foods are equally acidifying.

A Load of Acid to Kidney Evaluation (LAKE) score has been developed to take into account both the acid load of foods and their typical serving sizes. It can be used to help people modify their diet for the prevention of both uric acid and calcium kidney stones, as well as other diseases. What did researchers find? The single most acid-producing food is fish, like tuna. Then, in descending order, are pork, then poultry, cheese (though milk and other dairy are much less acidifying), and beef followed by eggs. (Eggs are actually more acidic than beef, but people tend to eat fewer eggs in one sitting.) Some grains, like bread and rice, can be a little acid-forming, but pasta is not. Beans are significantly alkaline-forming, but not as much as fruits or even better, vegetables, which are the most alkaline-forming of all.

Through dietary changes alone, we may be able to dissolve uric acid stones completely and cure patients without drugs or surgery.

To summarize, the most important things we can do diet-wise is to drink 10 to 12 cups of water a day, reduce animal protein, reduce salt, and eat more vegetables and more vegetarian.

Want to try to calculate their LAKE score for the day? Just multiply the number of servings you have of each of the food groups listed in the graph in the video times the score.

Treating Kidney Stones with Diet

Treating Kidney Stones with Diet.jpeg

Studies suggest that excessive consumption of animal protein poses a risk of kidney stone formation, likely due to the acid load contributed by the high content of sulfur-containing amino acids in animal protein, a topic I explore in my video, Preventing Kidney Stones with Diet. What about treating kidney stones, though? I discuss that in How to Treat Kidney Stones with Diet. Most stones are calcium oxalate, formed like rock candy when the urine becomes supersaturated. Doctors just assumed that if stones are made out of calcium, we simply have to tell people to reduce their calcium intake. That was the dietary gospel for kidney stone sufferers until a 2002 study published in the New England Journal of Medicine pitted two diets against one another--a low-calcium diet versus a diet low in animal protein and salt. The restriction of animal protein and salt provided greater protection, cutting the risk of having another kidney stone within five years in half.

What about cutting down on oxalates, which are concentrated in certain vegetables? A recent study found there was no increased risk of stone formation with higher vegetable intake. In fact, greater dietary intake of whole plant foods, fruits, and vegetables were each associated with reduced risk independent of other known risk factors for kidney stones. This means we may get additional benefits bulking up on plant foods in addition to just restricting animal foods.

A reduction in animal protein not only reduces the production of acids within the body, but should also limit the excretion of urate, uric acid crystals that can act as seeds to form calcium stones or create entire stones themselves. (Uric acid stones are the second most common kidney stones after calcium.)

There are two ways to reduce uric acid levels in the urine: a reduction of animal protein ingestion, or a variety of drugs. Removing all meat--that is, switching from the standard Western diet to a vegetarian diet--can remove 93% of uric acid crystallization risk within days.

To minimize uric acid crystallization, the goal is to get our urine pH up to ideally as high as 6.8. A number of alkalinizing chemicals have been developed for just this purpose, but we can naturally alkalize our urine up to the recommended 6.8 using purely dietary means. Namely, by removing all meat, someone eating the standard Western diet can go from a pH of 5.95 to the goal target of 6.8--simply by eating plant-based. As I describe in my video, Testing Your Diet with Pee & Purple Cabbage, we can inexpensively test our own diets with a little bathroom chemistry, for not all plant foods are alkalinizing and not all animal foods are equally acidifying.

How Much Nutrition Education Do Doctors Get?

How Much Nutrition Education Do Doctors Get?.jpeg

In the United States, most deaths are preventable and related to nutrition. Given that the number-one cause of death and the number-one cause of disability in this country is diet, surely nutrition is the number-one subject taught in medical school, right? Sadly, that is not the case.

As shown in my video, Physician's May Be Missing Their Most Important Tool, a group of prominent physicians wrote in 2014 that "nutrition receives little attention in medical practice" and "the reason stems, in large part, from the severe deficiency of nutrition education at all levels of medical training." They note this is particularly shocking since it has been proven that a whole foods, plant-based diet low in animal products and refined carbohydrates can reverse coronary heart disease--our number-one killer--and provide potent protection against other leading causes fof death such as cancer and type 2 diabetes.

So, how has medical education been affected by this knowledge? Medical students are still getting less than 20 hours of nutrition education over 4 years, and even most of that has limited clinical relevance. Thirty years ago, only 37 percent of medical schools had a single course in nutrition. According to the most recent national survey, that number has since dropped to 27 percent. And it gets even worse after students graduate.

According to the official list of all the requirements for those specializing in cardiology, Fellows must perform at least 50 stress tests, participate in at least 100 catheterizations, and so on. But nowhere in the 34-page list of requirements is there any mention of nutrition. Maybe they leave that to the primary care physicians? No. In the official 35-page list of requirements for internal medicine doctors, once again, nutrition doesn't get even a single mention.

There are no requirements for nutrition before medical school either. Instead, aspiring doctors need to take courses like calculus, organic chemistry, and physics. Most of these common pre-med requirements are irrelevant to the practice of medicine and are primarily used to "weed out" students. Shouldn't we be weeding out based on skills a physician actually uses? An important paper published in the Archives of Internal Medicine states: "The pernicious and myopic nature of this process of selection becomes evident when one realizes that those qualities that may lead to success in a premedical organic chemistry course...[like] a brutal competitiveness, an unquestioning, meticulous memorization, are not necessarily the same qualities that are present in a competent clinician."

How about requiring a course in nutrition instead of calculus, or ethics instead of physics?

Despite the neglect of nutrition in medical education, physicians are considered by the public to be among the most trusted sources for information related to nutrition. But if doctors don't know what they're talking about, they could actually be contributing to diet-related disease. If we're going to stop the prevailing trend of chronic illness in the United States, physicians need to become part of the solution.

There's still a lot to learn about the optimal diet, but we don't need a single additional study to take nutrition education seriously right now. It's health care's low-hanging fruit. While we've had the necessary knowledge for some time, what we've been lacking is the will to put that knowledge into practice. If we emphasized the powerful role of nutrition, we could dramatically reduce suffering and needless death.

Take, for example, the "Million Hearts" initiative. More than 2 million Americans have a heart attack or stroke each year. In 2011, U.S. federal, state, and local government agencies launched the Million Hearts initiative to prevent 1 million of the 10 million heart attacks and strokes that will occur in the next 5 years. "But why stop at a million?" a doctor asked in the American Journal of Cardiology. Already, we possess all the information needed to eradicate atherosclerotic disease, which is our number-one killer while being virtually nonexistent in populations who consume plant-based diets. Some of the world's most renowned cardiovascular pathologists have stated we just need to get our cholesterol low enough in order to not only prevent--but also reverse--the disease in more than 80% of patients. We can open up arteries without drugs and surgery, and stabilize or improve blood flow in 99% of those who choose to eat healthily and clean up their bad habits. We can essentially eliminate our risk of having a heart attack even in the most advanced cases of heart disease.

Despite this, medical students aren't even taught these concepts while they're in school. Instead, the focus is on cutting people open, which frequently provides only symptomatic relief because we're not treating the actual cause of the disease. Fixing medical education is the solution to this travesty. Knowledge of nutrition can help doctors eradicate the world's leading killer.

I've previously addressed how Doctors Tend to Know Less Than They Think About Nutrition, which is no surprise given most medical schools in the United States fail to provide even a bare minimum of nutrition training (see Medical School Nutrition Education), with mainstream medical associations even actively lobbying against additional nutrition training.
